Cold rolled steel coil is hot rolled steel coil as raw material, after pickling to remove the oxide skin for cold continuous rolling, the finished product is rolled hard coil, due to continuous cold deformation caused by cold hardening of rolled hard coil strength, hardness, toughness and plastic indexes decline, so the stamping performance will deteriorate, can only be used for simple deformation of the parts. Rolled rolls can be used as raw materials for hot-dip galvanising plants, because hot-dip galvanising units are equipped with annealing lines. Rolled hard coil weight is generally 6 ~ 13.5 tonnes, the inner diameter of the coil is 610mm/508mm.
General cold rolled plates and coils should be continuously annealed (CAPL unit) or annealed in the hood furnace to eliminate cold hardening and rolling stress, to achieve the mechanical properties specified in the corresponding standards.
Cold rolled steel plate surface quality, appearance, dimensional accuracy are better than hot rolled plate, and the thickness of its products right rolled thin to 0.18mm or so, so favoured by the majority of users. Cold rolled steel coil as a substrate for the deep processing of products, become high value-added products. Such as electro-galvanized, hot-dip galvanized, fingerprint-resistant electro-galvanized, colour-coated steel coils and vibration-damping composite steel, PVC laminated steel.
Advantages of cold rolled steel:
(1) Higher precision, cold rolled strip thickness difference of no more than 0.01~0.03mm.
(2) Thinner dimensions, cold rolled thinnest can be rolled 0.001mm steel strip; hot rolled can now be as thin as 0.78mm.
(3) Superior surface quality, cold rolled steel plate can even produce a mirror surface; while the surface of the hot rolled plate has iron oxide,pockmarks and other defects.
(4) Cold rolled plate can be adjusted according to user requirements of its school performance such as tensile strength and process performance such as stamping performance.
